10-Acetyl-3,7-dihydroxyphenoxazine (ADHP) is a highly sensitive and stable substrate for horseradish peroxidase (HRP). It enables selective detection of H2O2. This colorless, non-fluorescent reagent reacts with H2O2 to produce the fluorescent compound resorufin, which can be analyzed.
APTS is a fluorescence reagent that has a high level of detection sensitivity for sugars. The LOD for APTS-derivatized sugars has been proven to be 0.4 nM when using a 488 nm laser. The tri-anionic nature of APTS makes it ideal for the studies of carbohydrate molecules and small hormone molecules by high resolution capillary electrophoresis.
Homobifunctional cross-linking reagent; e.g. isolation of insulin receptor
DSG is disuccinimidyl glutarate, a simple homobifunctional crosslinker builded on the amine-reactive N-hydroxysuccinimide (NHS) ester group at both sidws of a 7.7 angstrom spacer arm. It is used for crosslinking the amine moiety of several molecules. DSG is cell membrane-permeable and it is used in ChIP assays to determine DNA-protein binding interactions.
